How to use val.py to calculate mAP on custom testing dataset of YOLOv5?

Question

I am trying to calucate mAP on my testing dataset using this:

!python val.py  --task test

I am using a custom data.yaml file. But I don't know how to point to that data.yaml. And when I use the following code:

val.py --data= /content/data.yaml --task test

The model outputs an invalid argument error. Also by default it is trying to calculate mAP on coco.yaml.

You shall use val instead of test value for task parameter like as below.

python val.py --weights {{model}} --data data.yaml --task val
